Description

The present invention relates to an image forming apparatus.

Nowadays, the image forming apparatus supports a function of saving power (hereinafter referred to as a sleep operation mode) such as turning off the power of some devices in order to reduce power consumption. However, when the user uses the image forming apparatus from the sleep operation mode, a waiting time is required until the user returns from the sleep operation mode to the normal operation mode by performing the touch panel input or the key input. In order to shorten the waiting time, there are the following technologies using a motion sensor.
The image forming apparatus described in Patent Document 1 changes the sensitivity of the motion sensor by memorizing the detection state of the motion sensor and the usage status by the user at a fixed time. The image forming device returns from the sleep operation mode to the normal operation mode by using the motion sensor. Unlike the normal return factor, the sleep operation mode changes to the normal operation mode even when a user who does not want to use the image approaches. There is a possibility that a false detection of returning to will occur. In order to solve this problem, there is a technique for changing the sensitivity of the motion sensor as in Patent Document 1.

The power supply unit 219 supplies electric power to each part constituting the management server 200.

Subsequently, the setting process of the motion sensor unit 11 will be described with reference to FIGS. 1 to 5.

2 and 3 are flowcharts showing the setting process of the motion sensor unit 11. The setting process of the motion sensor unit 11 is a process in which the control unit 10 sets the detection degree of the motion sensor unit 11 based on the instruction for setting the detection degree of the motion sensor unit 11. For example, when the power of the image forming apparatus 100 is turned on, the control unit 10 starts the setting process of the motion sensor unit 11.

Step S301: The control unit 10 receives an instruction signal. The control unit 10 keeps processing in this step state until it receives the instruction signal. The instruction signal indicates an instruction for adjusting the detection degree setting of the motion sensor unit 11. The instruction signal includes the sensor strength of the motion sensor unit 11. In the embodiment of the present invention, when the user presses the operation key 22 of the operation unit 2, the control unit 10 displays the first notification screen G1 for changing the setting of the motion sensor unit 11 on the display of the touch panel 21. Let me. The first notification screen G1 will be described later with reference to FIG. In the embodiment of the present invention, the control unit 10 generates an instruction signal based on the user's operation on the first notification screen G1, but generates an instruction signal according to a predetermined program of the image forming apparatus 100. You may.

When the control unit 10 receives an operation instruction indicating that the press of the button (YES button shown in FIG. 4) corresponding to the permission to change the setting is detected on the first notification screen G1, the user sets the first notification screen G1. The process is moved to step S303 while maintaining the changed detection degree as the temporarily set detection degree. The temporary setting is an example of "temporary adjustment", and indicates that the value of the detection degree can be returned to the value before the adjustment (that is, the change of the detection degree is not confirmed). When the control unit 10 receives an operation instruction indicating that the button (NO button shown in FIG. 4) corresponding to the rejection of the setting change is detected on the first notification screen G1, the value of the detection degree of the setting change is received. Is returned to the value before displaying the first notification screen G1, and the process is stopped in step S301.

Step S303: The control unit 10 determines whether or not notification to the administrator is required before changing the setting. When the advance notification flag of the storage unit 9 is on (Yes in step S303), the control unit 10 shifts the process to step S305. When the advance notification flag of the storage unit 9 is off (No in step S303), the control unit 10 shifts the process to step S311.

Step S305: The control unit 10 notifies the administrator of the instruction signal. For example, the control unit 10 notifies the management server 200 of the instruction signal via the communication unit 8. Note that the notification to the administrator who uses the management server 200 may use an e-mail in a specific format having a YES button and a NO button.

Step S307: The control unit 210 of the management server 200 determines whether or not to allow the setting change based on the input from the administrator. Specifically, first, the communication unit 208 of the management server 200 receives the instruction signal and transmits the instruction signal to the control unit 210. Then, the control unit 210 causes the display of the touch panel 221 to display the second notification screen G2. The administrator refers to the second notification screen G2, determines whether or not to change the setting of the motion sensor unit 11, and inputs the determination result to the operation unit 202. The second notification screen G2 will be described later with reference to FIG. 5A.

The control unit 210 of the management server 200 received an operation instruction from the touch panel 221 indicating that the pressing of the button (YES button shown in FIG. 5A) corresponding to the permission to change the setting was detected on the second notification screen G2. At the time (Yes in step S307), an adjustment instruction to adjust the detection degree is transmitted to the image forming apparatus 100 via the communication unit 208. The control unit 10 shifts the process to step S311 while maintaining the detection degree for which the setting has been changed. Further, when the control unit 10 receives an operation instruction from the touch panel 221 indicating that the button corresponding to the rejection of the setting change (NO button shown in FIG. 5A) has been pressed (No in step S307), the step The process is transferred to S309.

Step S309: The control unit 210 of the management server 200 notifies the image forming apparatus 100 of the disapproval of the setting change. Specifically, the control unit 210 transmits an adjustment instruction not to adjust the detection degree to the image forming apparatus 100 via the communication unit 208. The control unit 10 shifts the process to step S310.

Step S310: The control unit 10 returns the detection degree setting to the value at the start. Specifically, the control unit 10 returns the value of the detection degree whose setting has been changed in step S301 to the value of the detection degree before displaying the first notification screen G1, and shifts the process to step S301.

By executing steps S303 to S310, the temporarily set detection degree can be returned to the original value, so that it is possible to prevent the detection degree of the motion sensor unit 11 from becoming too high or too weak. To do.

Step S311: The control unit 10 adjusts the setting of the motion sensor unit 11. Specifically, the control unit 10 sets the detection degree whose setting has been changed to the motion sensor unit 11.

Step S313: The control unit 10 monitors the usage status of the motion sensor unit 11. The control unit 10 collects return information during the unit time Ts in order to monitor the usage status of the image forming apparatus 100. The return information indicates the time when the control unit 10 receives the detection signal generated by the motion sensor unit 11 and the time when the control unit 10 receives the operation signal generated by the operation unit 2. The unit time Ts is, for example, 30 minutes, and indicates the time from the time when the process of step S313 is started to the time when a certain time has elapsed. The unit time Ts is an example of "predetermined time". The control unit 10 stores the return information in the storage unit 9.

Step S315: The control unit 10 notifies the administrator of the reception signal. As described with reference to FIG. 1, the reception signal includes a time when the control unit 10 receives the detection signal within the unit time Ts and an operation presence / absence signal indicating whether or not the operation unit 2 has received the operation instruction. Including. Specifically, the control unit 10 reads the time when the detection signal is received and the operation presence / absence signal from the storage unit 9 to create a reception signal. Then, the correspondence table T3 is created based on the reception signal. The operation presence / absence signal indicates whether or not the operation unit 2 generates the operation signal within a short time (for example, 10 seconds) after the time when the control unit 10 receives the detection signal. The control unit 10 transmits the correspondence table T3 to the management server 200 via the communication unit 8 and notifies the administrator. The process proceeds to step S317 shown in FIG.

Step S317: The control unit 210 of the management server 200 determines whether or not to allow the setting change based on the input from the administrator. Specifically, first, the communication unit 208 of the management server 200 receives the correspondence table T3 and transmits the correspondence table T3 to the control unit 210. Then, the control unit 210 causes the display of the touch panel 221 to display the third notification screen G3. The administrator refers to the third notification screen G3, determines whether or not to change the setting of the motion sensor unit 11, and inputs the determination result to the operation unit 202. The third notification screen G3 will be described later with reference to FIG. 5 (b).

When the control unit 210 of the management server 200 receives an operation instruction from the touch panel 221 indicating that the button corresponding to the setting change (YES button shown in FIG. 5B) has been pressed on the third notification screen G3 ( Yes) in step S317, an adjustment instruction to adjust the detection degree is transmitted to the image forming apparatus 100 via the communication unit 208. The control unit 10 of the image forming apparatus 100 shifts the process to step S319 while maintaining the detection degree for which the setting has been changed. Further, when the control unit 10 receives an operation signal from the touch panel 221 indicating that the button corresponding to the rejection of the change (NO button shown in FIG. 5B) has been pressed (No in step S317), step S321 Move the process to.

Step S319: The control unit 10 sets a time during which the setting of the motion sensor unit 11 can be changed. Since the adjustment instruction to adjust the detection degree is received in step S317, the current detection degree value of the motion sensor unit 11 is regarded as this setting. This setting is an example of "main adjustment", and indicates that the value of the detection degree cannot be returned to the value before the adjustment (that is, the change of the detection degree is confirmed). In the embodiment of the present invention, the change of the detection degree of the motion sensor unit 11 is restricted until a preset time (time for restricting the adjustment of the detection degree) elapses. The preset time is, for example, 6 hours. When steps S311 to S319 are executed, it is possible to prevent the setting change from being excessively executed.

In the embodiment of the present invention, the time during which the setting can be changed is set in advance before step S319 is executed. However, in addition to the adjustment instruction in step S317, the control unit 210 of the management server 200 may transmit time information indicating the time for restricting the adjustment of the detection degree to the image forming apparatus 100 via the communication unit 208. ..

Step S321: The control unit 210 of the management server 200 notifies the image forming apparatus 100 of the disapproval of the setting change. Specifically, the control unit 210 transmits an adjustment instruction not to adjust the detection degree to the image forming apparatus 100 via the communication unit 208. The control unit 10 shifts the process to step S323.

Step S323: The control unit 10 returns the detection degree setting to the value at the start. The control unit 10 returns the value of the detection degree whose setting has been changed in step S301 to the value of the detection degree before displaying the first notification screen G1, and shifts the process to step S301.

Step S325: The control unit 10 does not accept an instruction to change the setting of the motion sensor unit 11 from the user until a certain time (for example, a preset time) has elapsed. The control unit 10 shifts the process to step S301 after the preset time has elapsed. By executing steps S301 to S325, the administrator can monitor the operating status of the motion sensor unit 11 of the image forming apparatus 100. Further, the administrator can determine whether or not the sensitivity of the motion sensor unit 11 can be changed while considering the balance between the convenience of the user and the power consumption.

Next, a display example (first notification screen G1) of the image forming apparatus 100 will be described with reference to FIG. FIG. 4 is a diagram showing a display example of the image forming apparatus 100. The control unit 10 of the image forming apparatus 100 displays the first notification screen G1 on the display of the touch panel 21.

As shown in FIG. 4, the first notification screen G1 shows a level meter for displaying the sensor intensity and four buttons for changing the setting of the motion sensor unit 11. The four buttons are the YES button B1, the NO button C1, the DOWN button D1, and the UP button E1. The touch panel 21 detects that the object to be detected is pressed at the position where each button is displayed, and transmits an operation instruction to the control unit 10. When the control unit 10 receives an operation instruction based on the detection of pressing the DOWN button D1, the control unit 10 lowers the detection degree of the motion sensor unit 11 and changes the display of the level meter. Similarly, when the control unit 10 receives an operation instruction based on the detection of pressing the UP button E1, the control unit 10 raises the detection degree of the motion sensor unit 11 and changes the display of the level meter.

For example, when the YES button B1 is pressed in step S301 shown in FIG. 2 when executing the setting change of the motion sensor unit 11, the control unit 10 of the image forming apparatus 100 shifts the process to step S303. When the NO button C1 is pressed in step S301, the control unit 10 of the image forming apparatus 100 keeps the process in step S301.

Next, a display example of the management server 200 (second notification screen G2 and third notification screen G3) will be described with reference to FIG. FIG. 5 is a diagram showing a display example of the management server 200. The control unit 210 of the management server 200 displays the second notification screen G2 on the display of the touch panel 221. As shown in FIG. 5A, the second notification screen G2 shows an area indicating “image forming apparatus No. X”, an area indicating “request for approval of setting change”, and “sensor strength Y”. Two buttons for changing the settings of the area and the motion sensor unit 11 are shown. The two buttons are the YES button B2 and the NO button C2. The X is a number for identifying the image forming apparatus 100 for which the setting has been changed, and the Y is a value indicating the sensor strength.

For example, when the YES button B2 is pressed in step S307 shown in FIG. 2 when the setting of the motion sensor unit 11 is changed, the control unit 210 of the management server 200 gives an adjustment instruction to adjust the detection degree. Is transmitted to the image forming apparatus 100 via the communication unit 208. The control unit 10 of the image forming apparatus 100 shifts the process to step S311 while maintaining the detection degree for which the setting has been changed. When the NO button C2 is pressed in step S307, the control unit 210 shifts the process to step S309.

Further, the control unit 210 of the management server 200 displays the third notification screen G3 on the display of the touch panel 221. As shown in FIG. 5 (b), on the third notification screen G3, the area showing "image forming apparatus No. X", the area showing "sensor intensity Y", the correspondence table T3, and the motion sensor unit 11 Two buttons for changing settings are shown. The two buttons are the YES button B3 and the NO button C3. The X is a number for identifying the image forming apparatus 100 for which the setting has been changed, and the Y is a value indicating the sensor strength. In the correspondence table T3, the time when the control unit 10 receives the detection signal and the presence / absence of the operation signal within a short time (for example, 10 seconds) from the reception time are recorded.

Subsequently, the contents of the correspondence table T3 will be described. For example, when the time detected for the first time is 00:00:01, the presence / absence of the operation signal is “Yes”. When the time detected for the second time is 00:01:45, the presence / absence of the operation signal is “none”. This is an example in which a person approaches the image forming apparatus 100 at 0:00:01, a person performs some operation, and leaves the image forming apparatus 100 at 00:01:45. Further, when the time detected for the fifth time is 00:13:33, the presence / absence of the operation signal is “none”. This is an example in which a person passes in front of the image forming apparatus 100 without operating the image forming apparatus 100. As shown in FIG. 5B, the control unit 10 received the detection signal 8 times and the operation signal “yes” 4 times in 30 minutes from 00:00. .. The administrator determines whether or not it is necessary to change the setting of the motion sensor unit 11 with reference to the correspondence table T3.

For example, when the YES button B3 is pressed in step S317 shown in FIG. 3 when executing the setting change of the motion sensor unit 11, the control unit 210 of the management server 200 gives an adjustment instruction to adjust the detection degree. Is transmitted to the image forming apparatus 100 via the communication unit 208. The control unit 10 of the image forming apparatus 100 shifts the process to step S319 while maintaining the detection degree for which the setting has been changed. Further, when the NO button C3 is pressed in step S317, the control unit 210 shifts the process to step S321.
